The TicTacLights Colour is the RGB version of the TicTacLights, a very small BlinkenLights clone that fits inside a small TicTac box. Unlike the monochrome version, the TicTacLights Colour requires a 5 V power supply, e.g. a USB port. The PCB has a Mini-USB-B connector and internal pads for a possible battery supply (e.g. a lithium-ion battery with a switching converter for constant 5 V).

This project uses the BlinkenPlus firmware on an ATmega162 controller. The PCB has pads for a Micro-SD card slot and solder pads for a serial port (5 V level, RS232-compatible with external level converter, e.g. MAX232).

Hardware

The hardware is very similar to the Blinkström Colour, the only difference is that the rows are driven directly from the controller rather than through MOSFRETs. This is possible because the TicTacLights Colour uses a lower LED current than the Blinkström Colour.

The 3.3 V supply for the SD card is generated by a linear regulator. The maximum current draw of the circuit (all LEDs white at maximum brightness) is approx. 250 mA, not including the current consumption of the SD card (if inserted).
